**What is color blindness?** == Color blindness is a genetic disease where some people have the inability to see 1 or more colors. And you may also see those colors as other colors. For example, you might see blue as white or gray and yellow as white and gray. Color blindness is a genetic disease that rarely shows up in females, but it occurs in 1 out of 10 males to some degree. Color blindness occurs when there is a problem with the color-sensing materials in certain nerve cells of the eyes. The most severe case of color blindness is achromatopisa, where you cannot see any color. There is a drug called hydroxychloroquine that can also cause color blindness. Color blindness has no known treatment and lasta a life-time. Color blindness doesn't mean that a person sees in black and white, it simply means that they have trouble seeing the difference between 2 colors. ==

How is color blindness inherited or how if not by inheritance?
==Color blindness is an inherited through the X chromosome, usually from the mom. Even if the mom doesn't have the disease, she is still a carrier through the X chromosome. Males usually get the disease because they only possess 1 X chromosome. For a women to inherit color blindness, she must get the defective X chromosome from both of her parents. If you have color blindness, but you did not inherit it, you probably got it because of aging, eye problems, or injury to the eye. You could also maybe get it as a side affect of some medicine. ==

How can you tell if you are colorblind?
==You can tell that you are color blind if, for example, you mom tells you to get her her purple sandals and you give her blue ones. Or if you confuse orange and pink(you may not confuse these colors, these are just examples). Your mom or dad will probably take you to an eye doctor and get your eyes professionally checked for color blindness. You can also take multiple color blindness tests online. If you get "wrong" for all of the questions or the majority of the questions, you are probably color blind. If you get them all "right" you are probably not color blind. But, I highly recommend that if you are not sure if youare or are not, go to an eye doctor an get your eyes professionally checked. ==
